Title: Rotary compressor
Inventor: TANAKA YASUHIKO
IPC: F04C28/06
Filed: 1984-12-27
Abstract: PURPOSE:To rapidly form a required differential pressure between a high and low pressure side for a valve and ensure its opening force, by constituting the high pressure valve so as to simultaneously close a high pressure side inlet and outlet port and preventing an inflow of gas in an enclosed vessel to a low pressure side port when a compressor is started. CONSTITUTION:A disc-shaped valve 55 integrally provides a high pressure valve part 55a, having a size able to simultaneously close a high pressure side outlet port 53 and inlet port 54, with a low pressure valve part 55b in an opposite side, and the valve 55, being slidably housed in a casing 51, is continually urged to the high pressure side ports 53, 54 by a bias spring 56. By such constitution, a compressor, closing at the time of its starting the high pressure side inlet port 54 by the high pressure valve part 55a, causes a factor disturbing a pressure drop in a low pressure side port 52 to be generated by a quantity of gas due to leakage in the high pressure side inlet port 54 and the high pressure valve part 55a, performing a very rapid pressure drop as compared with those always communicating with an enclosed vessel 1. In this way, the compressor, rapidly forming a required differential pressure between a high and a low pressure side operating the valve 55, enables its opening force to be ensured.

Title: Light receiving circuit having excessive-light-input alarming circuit
Inventor: NAKAI TAKAO
IPC: H04B10/07
Filed: 1988-11-04
Abstract: PURPOSE:To issue an alarm with respect to an excessive light input level and to make it possible to judge whether light input is excessively large or excessively small simply by outputting a signal from the comparison between the divided voltage of a bias voltage which is imparted to a photodetector and a specified reference voltage. CONSTITUTION:An APD (photodetector) 1 transduces an inputted light signal into an electric signal. The signal is amplified in an equalizing amplifier 2 through a capacitor 13. A gain control voltage is detected out of a part of the amplified signal with an amplitude detecting circuit D. A DC/DC converter circuit 3 outputs the DC voltage corresponding to the output and imparts a bias voltage to the APD 1. Thus the optimum multiplication factor is obtained at the minimum receiving sensitivity of a light receiver. These loop circuits form a negative feedback circuit by which the signal from the APD 1 is made large as much as possible and the noise are made small. The bias voltage is divided, and the voltage is compared with a specified reference voltage (a) in a comparator 8. The voltage of the APD 1 is inversely proportional to the input power of the light. From this characteristic, an excessive light input alarm (b) is outputted when the divided voltage becomes smaller than the voltage (a).

Title: Production of grain oriented silicon steel sheet extremely excellent in core loss and roll
Inventor: MASUI HIROAKI
IPC: C21D8/12
Filed: 1993-11-09
Abstract: PURPOSE:To produce a grain oriented silicon steel sheet excellent in magnetic properties. CONSTITUTION:A kind of so-called intermediate-stage magnetic domain controlling method is used. At the time of preparing a mirror finished material, grooves are formed by means of a roll in a steel sheet after primary annealing. At the time of pressing, the fact that, when rolling is applied to the primary- annealed steel sheet to which a powder of oxide, chloride, or sulfide is allowed to adhere by using a roll having projections, the powder is press-fixed and does not fall is led by a theoretical formula. As a result, the production of the sheet with ultralow core loss by combining the control of intermediate magnetic domain with the dry application of powder is made possible. By this method, the magnetic domain fractionized grain oriented silicon steel sheet can be produced.
